I have not used it. I'm mentioning it because you mentioned unification and prolog and because you basically want a two-way function, which is what was touted as the ideal use-case for core.logic when it was heavily discussed on this list a few months (years?) ago.
I'm not aware of the details of the performance tradeoffs, though. I imagine it would be slower than writing both functions by hand, but I have no idea how much.
